Have You Tried Sam's Club Cream Cheese Frosting?

I will be making between 30 and 50 carrot cakes in the coming weeks. I am doing them for charity, so I am trying very hard to keep my costs down. I can buy a bucket of Sam's cream cheese frosting for a very resonable price. It is also shelf stable, which is an important factor. Has anybody tried this frosting? Opinions? Thanks so much!
